Serum cortisol fully mediates the relationship between fecal Ruminococcus and MRS-derived brain N-acetylaspartate. First, fecal Ruminococcus negatively predicted MRS-derived brain NAA concentrations (path A). Second, fecal Ruminococcus negatively predicted serum cortisol concentrations (path B). Third, mediation effects were assessed for serum cortisol concentrations. The indirect effect (i.e., the effect of fecal Ruminococcus through serum cortisol on MRS-derived brain NAA; path B × C) was significant, and the direct effect (path A’) was not significant. Thus, serum cortisol fully mediates the relationship between fecal Ruminococcus and MRS-derived brain NAA. Abbreviation: N-acetylaspartate (NAA).

Recent studies show microbes can influence human health, behavior, and certain neurologic...

>>according to the findings of a preliminary study presented today at the Society for Endocrinology annual conference in Edinburgh. Vitamin D, which is both a vitamin and a hormone, helps control levels of calcium and phosphate in the blood and is essential for the formation of bones and teeth. Sources of Vitamin D include oily fish and eggs, but it can be difficult to get enough through diet alone. Most people generate vitamin D by exposing their skin to UVB rays in sunlight.

Previous studies suggest that vitamin D can block the action of enzyme 11-βHSD1, which is needed to make cortisol. High levels of cortisol may raise blood pressure by restricting arteries, narrowing blood vessels and stimulating the kidneys to retain water...
